Define the relаtiоnship between genetic disоrders аnd cоngenitаl disorders, explaining why Down syndrome is classified as both, while Huntington's disease is considered only genetic and Fetal Alcohol Syndrome is considered only congenital. Furthermore, describe TWO reasons why advanced maternal age (past 35) increases the risk of a child being born with a chromosomal abnormality. The relationship between genetic and congenital disorders is based on their origin and the timing of their clinical manifestation. Genetic disorders are caused by abnormalities in the genome, such as chromosomal aberrations or gene mutations. Congenital disorders are those whose clinical manifestations are evident at the time of birth, regardless of the underlying cause. The sources differentiate these categories using specific examples: • Down Syndrome (Both): It is genetic because it involves a change in the genome (specifically having three copies of chromosome 21) and congenital because its physical heart defects and facial features are observable at birth. • Huntington’s Disease (Genetic Only): This is characterized by a defective huntingtin gene, but it is not congenital because symptoms typically do not appear until a person is in their mid-30s. • Fetal Alcohol Syndrome (Congenital Only): While the manifestations are evident at birth, it is not a genetic disorder because it is caused by the environmental consumption of alcohol during pregnancy rather than a genetic mutation. Women over the age of 35 face an increased risk of chromosomal abnormalities, primarily due to the biological aging of their eggs. Unlike men, women are born with their entire lifetime supply of eggs, which age alongside them. This aging process leads to several critical failures: • Mitotic Spindle Breakdown: Over time, the molecular components of the mitotic spindle—specifically securin and cohesion proteins—begin to degrade. These proteins are responsible for the proper separation of chromosomes during meiosis; their breakdown leads to nondisjunction, where eggs are ovulated with an incorrect number of chromosomes. • Maternal Immune System Escape: In younger women, a strong immune system typically recognizes a genetically abnormal embryo as "non-self" or defective, resulting in a miscarriage (spontaneous abortion). However, as a woman ages, her immune system weakens, allowing these abnormal embryos to escape detection and destruction. Consequently, the pregnancy is carried to term, resulting in the birth of a child with a genetic disorder.
